Abstract:
Metallic powders are one of the most common feedstock materials for metal additive manufacturing (MAM). Nowadays, only few alloys can be processed by these technologies and most of them are casting alloys. This work is focused on the characterization of a novel aluminum alloy produced by a close coupled gas atomizer (CCGA) with composition AlSi10Mg + X Cu (X= 4, 8, 20 wt%). These compositions are very attractive because copper is a well-known strengthener for aluminum alloys. The produced powders were characterized in terms of morphology, flowability, particle size distribution (PSD) and density. Furthermore, the powders microstructures were analyzed to evaluate the composition and the morphology of the phases generated by the rapid solidification that characterized the gas-atomization process.
